Hi Herbert,

After merging the crypto tree, today's linux-next build (powerpc
ppc64_defconfig) produced these messages:

fs/sysfs/Kconfig:1:error: recursive dependency detected!

The x86_64 allmodconfig build produced these:

I am not sure exactly what caused all this, but it is probably commit
126ae9adc1ec ("crypto: ccp - Base AXI DMA cache settings on device
tree").

I have used the version of the crypto tree from next-20140723 for today.
